Voice over Internet Protocol, is called VoIP. Voice over IP (VoIP) implementations enable users to carry voice traffic (for example, telephone calls and faxes) over an IP network. VoIP (Voice over Internet Protocol) is one of the technologies behind the latest communication revolution. VoIP is changing the way companies communicate and do business.  If I have VoIP service, who can I call? You can be able to call any phone number, anywhere in the world. The call can be made to a local number, a mobile phone, to a long distance number, or an international number. You may even utilize the service to speak with more than one person at a time. The person you are calling does not need any special equipment, just a phone. How does it work? VoIP converts the voice signal from your telephone into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is then converted back at the other end. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone using an adapter. Advantages of VoIP
